Description
SKATE BOOT HAVING A MOLDED OUTSOLE WITH RAISED REGIONS
BACKGROUND OF THE INVENTION
7 . Field of the Invention The present invention is directed to skate boots for ice skating and inline skating, and, more specifically, to skate boots having a molded outsole that extends vertically about regions of the heel and toe, to capture and direct the transfer of energy from the skater to the blade chassis, and, in turn, the skating surface.
BACKGROUND OF THE INVENTION
7 . Field of the Invention The present invention is directed to skate boots for ice skating and inline skating, and, more specifically, to skate boots having a molded outsole that extends vertically about regions of the heel and toe, to capture and direct the transfer of energy from the skater to the blade chassis, and, in turn, the skating surface.
2. Background Art Skate boots of the type attached to blade chassis for use with ice skates or inline skates are well known in the art. Generally, the blade chassis is attached to a rigid base member or sole. The sole is generally of a single planar material which extends from the tae and ball of the boot to the heel of the boot. The upper portion of the skate boot meets the sole and is attached thereto.
Such a construction has certain drawbacks. The skater, while ! CA 02224897 1998-O1-23 able to transfer energy to the surface through the blade chassis, incurs significant energy losses. The energy from the skaters boot is transferred through the sole to the blade. At the same time, however, some of the energy generated by the skater is lost before it reaches the sole, and, in turn, the blade of the skate. Thus, some energy generated by the skater is not transferred to the blade chassis and the outside surface. The energy losses result in an overall loss of performance which is especially noticeable upon acceleration and turning or otherwise changing direction.
SUMMARY OF THE INVENTION
The skate boot comprises an outsole associated with a bottom of a boot upper, and includes a base member, at least one raised region and means for attaching a blade chassis to at least a portion of the base member. The base member includes an outer surface, a ball region and a heel region. The raised region is associated with at least one of the ball region and the heel region of the base member.
In a preferred embodiment, the raised region comprises a front raised region and a rear raised region. The front raised region is associated with the ball regiori of the base member. The rear raised region is associated with the heel region of the base member. In such a preferred embodiment, the front raised region may comprise two front raised regions positioned at substantially opposite sides of the ball region of the base member.
Preferably, the rear raised region may extend around the majority of the perimeter of the heel region. Moreover, the rear raised region may extend continuously around the perimeter of the heel region.
In another preferred embodiment, the base member may comprise a first rigid layer and a second rigid layer. The second rigid layer is overlyingly positioned over at least a portion of the first rigid layer. At least one of the first and second rigid layers extending into at least one of the at least one front raised region and the at least one rear raised region.

i; CA 02224897 1998-O1-23 ( .., DETAILED DESCRIPTION OF THE INVENTION
While the invention is susceptible of embodiment in many different forms, there is shown in the drawings, and will herein be described in detail, one specific embodiment, with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiment illustrated.
Skate boot 10 is shown in Figs. 1, 2, 5 and 6 as comprising boot uppers 12, blade chassis 13 and outsole 14 (Fig. 5 and Fig. 6). Boot uppers 12 include boot bottom 16 (Fig. 1 ), and, may comprise a conventional skate boot commonly used for ice skating; ice hockey, street hockey and/or inline skating. Blade chassis 13 (Fig. 5) comprises the carrier for a figure, speed or hockey skate blade as well as, analogously, wheels of an inline skate, or a street hockey skate.
Outsole 14 is shown in Figs. 4, 5 and 6 as comprising base member 18, raised regions 41 and attachment means 22 (Fig. 5 and 6).
Base member 18 comprises first rigid layer 24 and second rigid layer 26, and includes outer surface 28, ball region 30, arch region 31 and heel region 32. First rigid layer 24 (Figs. 1, 2 and 4-6) extends from ball region 30 to heel region 32.
Second rigid layer 26 is shown in Figs. 4~6 as comprising proximal second rigid layer 42 and distal second rigid layer 44. Proximal second rigid layer 42 is overiayingly positioned relative to first rigid layer 24 proximate ball region 30, and, extends over substantially the entirety of ball region 30. Distal second rigid layer 44 is similarly overlayingly positioned relative to first rigid layer 24 proximate heel region 32, and, extends over substantially the entirety of heel region 30. It is also contemplated that second rigid layer be positioned over arch region 31.
Raised regions 41 may include front raised regions, such as front raised regions 48, 48', 148, 148', as well as rear raised regions, such as rear raised region 50, 150. Front raised region 48Iis an extension of first rigid layer 24 which extends upwardly proximate the outer ball region of the foot. Front raised region 148 is an extension of proximal second rigid layer 42 that overlies front raised region 48. Front raised region 48' is an extension of first rigid layer 24 which extends upwardly proximate the inner ball region of the foot. Front raised region 148' is an extension of proximal second rigid layer 42 that overlies front raised region 48'. As such, the raised regions straddle the ball region and extend upward so as to essentially create a channel for the foot.
Rear raised region 50 is shown in Figs. 2, 5 and 6 as an extension of first rigid layer which extends upwardly around the perimeter of the heel, essentially from the inside of the heel region to the outside of the heel region. Rear raised region 150 is an extension of distal second rigid layer 44 that overlies rear raised region 50. As such, a cup of the heel region is created. While the rear raised region includes a continuous raised region, it is also contemplated that the heel region may comprise ,. t~', CA 02224897 1998-O1-23 two separate heel regions that straddle the heel region. Vertically, the rear raised regions extend a distance sufficient to effectively straddle or cup the heel.
The addition of raised regions 48, 48', 148, 148', 50 and 150 is valuable to the skater. The raised regions permit greater pressure from the skater's foot to be captured by the larger surface area on the outsole, and, in turn, the pressurelenergy is more effectively transmitted to the blade. Indeed, it has been determined that a meaningful additional transfer of energy can be obtained when the raised regions 48, 48' are approximately 1.25 inches and raised region 50 is approximately 1.50 inches at the sides. Empirically, it has been determined that the work transferred by the large raised regions may be in the area of 12-13 times greater than that which is available to the side regions of a conventional sole, or a sole with small raised regions. Such a gain provides noticeable advantages to the skater.
As shown in Figs. 5 and 6, blade chassis 13 is secured to the base member by attachment means 22, which may comprise a fastener 52 and conventional adhesive 54. Indeed, fastener 52 may comprise a rivet, screw, bolt or other conventional fastening means. In a preferred embodiment, fastener 52 extends through first rigid layer 24 and second rigid layer 26. Of course, other configurations for attachment are also contemplated, such as stitching and the like.
To fabricate base member 18, the material which will comprise second rigid layer 26 is introduced into the molding chamber.
Subsequently, the shape of the molding chamber is altered and material which will comprise the first rigid layer 24 is then introduced into the molding chamber. Although not required, an adhesive may be applied between the first and second rigid layers to increase the strength and to promote the bond therebetween. The front and rear raised regions are molded simultaneously with the molding of the first and second rigid layers.
To complete the skate boot, the completed outsole is associated with the bottom of the boot via any combination of adhesive, stitching and/or riveting. The blade chassis is then mounted, through attachment means 22 to the outsole (See Figs. 5 and 6).
In actual use, and for a better understanding of the benefits of the present invention, a skater wearing the previously described skate will experience more precise control and direct energy transfer between the foot, skate blade chassis and skating surface. As explained above, as a user desires to skate on the ice (or on the street in the case of in-line skates) the additional raised regions (when extending along a substantial vertical distance, as explained above) provide additional area to capture input from the skater and transfer same to the blade (or in-line chassis).
Accordingly, the skate becomes more responsive to the input of the skater, and less energy is lost.
The foregoing description and drawings are merely to explain and ~:::
illustrate the invention and the invention is not limited thereto except insofar as the appended claims are so limited, as those skilled in the art who have the disclosure before them will be able to make modifications and variations therein without departing from the scope of the invention.

Base member 18 comprises first rigid layer 24 and second rigid layer 26, and includes outer surface 28, ball region 30, arch region 31 and heel region 32. First rigid layer 24 (Figs. 1, 2 and 4-6) extends from ball region 30 to heel region 32.
Second rigid layer 26 is shown in Figs. 4~6 as comprising proximal second rigid layer 42 and distal second rigid layer 44. Proximal second rigid layer 42 is overiayingly positioned relative to first rigid layer 24 proximate ball region 30, and, extends over substantially the entirety of ball region 30. Distal second rigid layer 44 is similarly overlayingly positioned relative to first rigid layer 24 proximate heel region 32, and, extends over substantially the entirety of heel region 30. It is also contemplated that second rigid layer be positioned over arch region 31.
Raised regions 41 may include front raised regions, such as front raised regions 48, 48', 148, 148', as well as rear raised regions, such as rear raised region 50, 150. Front raised region 48Iis an extension of first rigid layer 24 which extends upwardly proximate the outer ball region of the foot. Front raised region 148 is an extension of proximal second rigid layer 42 that overlies front raised region 48. Front raised region 48' is an extension of first rigid layer 24 which extends upwardly proximate the inner ball region of the foot. Front raised region 148' is an extension of proximal second rigid layer 42 that overlies front raised region 48'. As such, the raised regions straddle the ball region and extend upward so as to essentially create a channel for the foot.
Rear raised region 50 is shown in Figs. 2, 5 and 6 as an extension of first rigid layer which extends upwardly around the perimeter of the heel, essentially from the inside of the heel region to the outside of the heel region. Rear raised region 150 is an extension of distal second rigid layer 44 that overlies rear raised region 50. As such, a cup of the heel region is created. While the rear raised region includes a continuous raised region, it is also contemplated that the heel region may comprise ,. t~', CA 02224897 1998-O1-23 two separate heel regions that straddle the heel region.

Such a gain provides noticeable advantages to the skater.
As shown in Figs. 5 and 6, blade chassis 13 is secured to the base member by attachment means 22, which may comprise a fastener 52 and conventional adhesive 54. Indeed, fastener 52 may comprise a rivet, screw, bolt or other conventional fastening means. In a preferred embodiment, fastener 52 extends through first rigid layer 24 and second rigid layer 26. Of course, other configurations for attachment are also contemplated, such as stitching and the like.
